Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552110, here are decompositions:

41 + 31552069 = 31552110
53 + 31552057 = 31552110
61 + 31552049 = 31552110
113 + 31551997 = 31552110
131 + 31551979 = 31552110
151 + 31551959 = 31552110
173 + 31551937 = 31552110
251 + 31551859 = 31552110

Showing the first eight; more decompositions exist.
